Answer:
11/-30 Hope this helped :)
Step-by-step explanation:
15x + 4 = -1 1/2
15x = -5 1/2
x = 11/-2*1/15
x = - 11/-30
Answer:
20 is 1/10 of 200
Step-by-step explanation:
20* 10 = 200
Answer:
2/3
Step-by-step explanation:
Since you need to find the mising number, I will give it the variable (v)
So the equation is now:
1½v is the same as 1½ x v
3½ + (1½v) = 4½
I need to undo addition so I subtract. To undo you need to look at the sign at the front of the number, since there was no negative sign I can infer that 3½ is positive. I need 3½ to cancel out and become 0, so I subtracted 3½ with 3½. What you do to one side of the equal sign, do to the other. 4½ subtract 3½ is 1.
The equation is now:
1½v = 1
I need to undo multiplication, so I divide 1½ by 1½. It cancels out, and I what you do to one side of the equal sign, you do to the other. 1 divides by 1½ is 2/3. (I used a calculator for this part)
Answer:
I don't know but I will find it bro don't worry
Answer:
(x + 10)(2x + 5)
Step-by-step explanation:
Given
2x² + 25x + 50
Consider the factors of the product of the coefficient of the x² term and the constant term (ac) which sum to give the coefficient of the x- term (b)
ac = 2 × 50 = 100 and b = 25
The factors are + 20 and + 5
Use these factors to split the x- term
2x² + 20x + 5x + 50 ( factor the first/second and third/fourth terms )
= 2x(x + 10) + 5(x + 10) ← factor out (x + 10) from each term
= (x + 10)(2x + 5)
